Abstract
A projection display unit with a detection function includes a projection display section () and a detector (). The projection display section () includes a display light source. The display light source emits light used as illumination light, and projects an image onto a projection surface with the illumination light. The detector () includes a detection light source that emits detection light. The detector () detects an object on or near the projection surface, and outputs a power-saving instruction signal to the projection display section () in accordance with a detection state of the object. The power-saving instruction signal instructs a transition to a power-saving mode. The projection display section () turns off the display light source in response to the power-saving instruction signal.
